The present disclosure relates to a window-shades mechanism, a fan device and an electronic apparatus, and more particularly, to a window-shades mechanism, a fan device and an electronic apparatus with an anti-backflow function.
A conventional fan mechanism includes a housing, a fan unit and a window-shades module. The housing has a sunken structure configured to accommodate the fan unit. A lateral wall of the housing has an opening structure where airflow can pass by. The window-shades module is disposed on the lateral wall of the housing and aligns with the opening structure. When the fan unit is turned off, blades of the window-shades module are lowered down to cover the opening structure, so the airflow cannot pass through the opening structure. When the fan unit is turned on, wind force generated by the fan unit can lift the blades of the window-shades module to expose the opening structure, therefore the airflow can pass through the opening structure. However, the conventional fan mechanism cannot provide preferred heat dissipating efficiency because a part of the wind force generated by the fan unit is consumed for lifting the blades of the window-shades module.
The present disclosure provides a window-shades mechanism, a fan device and an electronic apparatus with an anti-backflow function for solving above drawbacks.
According to the present disclosure, a window-shades mechanism with an anti-backflow function includes a supporter, a blade, a shaft and a connecting rod. The blade is disposed inside the supporter and includes two sides. Each side has a first region and a second region adjacent to each other. The shaft is connected to the supporter and the first region of the side of the blade. The connecting rod is connected to the second region of the side of the blade. The connecting rod has a holding portion. The connecting rod rotates the blade relative to the supporter via the shaft when the holding portion is moved by an external force.
According to the present disclosure, a fan device with an anti-backflow function includes a housing, at least one window-shades mechanism and a fan unit. The housing has a first wall and a second wall opposite to each other. The first wall and the second wall respectively includes a hole structure. The window-shades mechanism is disposed on one of the first wall and the second wall and corresponds to the hole structures. The window-shades mechanism includes a supporter, a blade, a shaft and a connecting rod. The supporter is connected to the housing. The blade is disposed inside the supporter and includes two sides. Each side has a first region and a second region adjacent to each other. The shaft is connected to the supporter and the first region of the side of the blade. The connecting rod is connected to the second region of the side of the blade. The connecting rod has a holding portion. The fan unit is detachably disposed inside the housing. The connecting rod rotates the blade relative to the supporter via the shaft when the fan unit presses the holding portion to move the connecting rod.
According to the present disclosure, an electronic apparatus with an anti-backflow function includes a base and a fan device. The base has a first area, a second area and a third area connected to each other. The fan device is disposed on the second area. The fan device includes a housing, at least one window-shades mechanism and a fan unit. The housing has a first wall and a second wall opposite to each other. The first wall and the second wall respectively includes a hole structure. The window-shades mechanism is disposed on one of the first wall and the second wall and corresponds to the hole structures. The window-shades mechanism includes a supporter, a blade, a shaft and a connecting rod. The supporter is connected to the housing. The blade is disposed inside the supporter and includes two sides. Each side has a first region and a second region adjacent to each other. The shaft is connected to the supporter and the first region of the side of the blade. The connecting rod is connected to the second region of the side of the blade. The connecting rod has a holding portion. The fan unit is detachably disposed inside the housing and located between the hole structures of the first wall and the second wall. The connecting rod drives the blade to rotate relative to the supporter via the shaft when the fan unit presses the holding portion and moves the connecting rod, so as to move the blade away from the hold structures and to connect the first area and the third area.
The window-shades mechanism of the present disclosure can connect the connecting rod with the plurality of blades, and the plurality of blades can be simultaneously and automatically rotated when the connecting rod is pushed by the fan unit. The blades can be automatically recovered in response to a removal of the fan unit. The window-shades mechanism can utilize one of the resilient component and the weighting component to recover the blades, or can utilize both the resilient component and the weighting component to recover the blades.
These and other objectives of the present disclosure will no doubt become obvious to those of ordinary skill in the art after reading the following detailed description of the preferred embodiment that is illustrated in the various figures and drawings.
Please refer to
In the embodiment, the housing 16 can have a first wall 22 and a second wall 24 opposite to each other, and the first wall 22 and the second wall 24 respectively has a hole structure 26. An amount of the hole structure 26 may equal an amount of the window-shades mechanism 18. Each window-shades mechanism 18 can be embedded in the corresponding hole structure 26. The fan unit 20 can be detachably disposed inside the housing 16, and located between two opposite window-shades mechanisms 18. As the fan unit 20 is not in the housing 16, the window-shades mechanism 18 located at the first wall 22 can turn off the blade 30 to cover the hole structure 26 for isolating the first area R1 from the second area R2, and the window-shades mechanism 18 located at the second wall 24 can turn off the blade 30 to cover the hole structure 26 for isolating the second area R2 from the third area R3, so as to prevent the airflow from turbulence. As the fan unit 20 is installed inside the housing 16, the blade 30 of the window-shades mechanism 18 can be lifted to expose the hole structure 26. It should be mentioned that amounts and positions of the fan unit 20 and the window-shades mechanism 18 are not limited to the above-mentioned embodiment; for example, the window-shades mechanism 18 may be only disposed on one of the first wall 22 and the second wall 24 corresponding to the related hole structure 26.

The shaft 32 can be rotatably connected to the inner lateral wall 40 of the supporter 28 and pivotally connected to the first region P1 of the blade 30. The connecting rod 34 can be rotatably connected to the second region P2 of the blade 30. The shaft 32 is spaced from the connecting rod 34, and a distance between the shaft 32 and the connecting rod 34 can be a level of force when the connecting rod 34 is pressed, so that the blade 30 can be rotated relative to the shaft 32 along a clockwise direction or along a counterclockwise direction. The connecting rod 34 can include a bridging portion 42 and a holding portion 44 bend from each other. The bridging portion 42 can be pivotally connected to the blade 30, and the holding portion 44 can be configured to hold the fan unit 20. When the holding portion 44 is pressed downwardly by the fan unit 20, the holding portion 44 can move the blade 30 via the bridging portion 42, and the blade 30 can be rotated relative to the supporter 28 via the shaft 32. One end 361 of the resilient component 36 can contact against the inner top wall 46 of the supporter 28, and the other end 362 of the resilient component 36 can contact against blade 30.

The window-shades mechanism 18″ in the third embodiment can include the resilient component 36 configured between the supporter 28 and the blade 30. The resilient recovering force of the resilient component 36 can move the blade 30 from position shown in
Please refer to
The sliding slot structure 50 and the sliding slot structure 50′ illustrated in the above-mentioned embodiment are straight sliding slots, and an actual shape of the sliding slot may depend on design demand. The sliding slot structure 50 and the sliding slot structure 50′ further can be designed as an arc sliding slot, or a sliding slot having a corner, or an elliptical sliding slot. Any sliding slot structure, which is capable of preventing the blade 30 from being moved out of the supporter 28 and have the related connecting rod 34 cooperate to operations of the fan unit 20, which indicate that the fan unit 20 being moved in or moved out from the housing 16, belong to a scope of the present disclosure.
Please refer to
The window-shades mechanism 52 can optionally include a recovering component 62 disposed on the actuating component 54 and contacting against the constraining structure 56. When the fan unit 20 is removed from the housing 16, a resilient recovering force of the recovering component 62 can push the actuating component 54 toward a direction opposite to the first direction D1 for recovery. The inclined guiding surfaces on the pressing portion 60 and the connecting rod 34′ in the foresaid embodiment are plane surfaces. However, the present disclosure further can design the pressing portion 60 as an inclined guiding convex structure and design the connecting rod 34′ as an inclined guiding concave structure, or design the pressing portion 60 as the inclined guiding concave structure and design the connecting rod 34′ as the inclined guiding convex structure. The pressed portion 58 may have the inclined guiding surface structure. When the fan unit 20 is installed into the housing 16 to press the pressed portion 58, the actuating component 54 can be moved by a horizontal component applied to the inclined guiding surface structure of the pressed portion 58, and the connecting rod 34′ can be lifted or lowered down due to motion of the actuating component 54.
In view of the above, the window-shades mechanism of the present disclosure can connect the connecting rod with the plurality of blades, and the plurality of blades can be simultaneously and automatically rotated when the connecting rod is pushed by the fan unit. The blades can be automatically recovered in response to a removal of the fan unit. It should be mentioned that the window-shades mechanism can utilize one of the resilient component and the weighting component to recover the blades, or can utilize both the resilient component and the weighting component to recover the blades. The fan device can be configured to hold the plurality of fan units. Even if some of the plurality of fan units may be removed, the window-shades mechanism without the corresponding fan unit can automatically lower down the blade, so that two independent barometric pressure areas respectively setting on two opposite sides of the fan device can keep stable barometric pressure, so as to provide preferred heat dissipating efficiency without airflow interference or backflow.
Those skilled in the art will readily observe that numerous modifications and alterations of the device and method may be made while retaining the teachings of the disclosure. Accordingly, the above disclosure should be construed as limited only by the metes and bounds of the appended claims.
